use jamvm with -Xbootclasspath option and specify the path to classes.zip and glibj.zip

to cortez: maybe you can unify and standardize the location of both jamvm and classpath to /usr/local/java (as the common --prefix). this would make locating all the related files easier, ie related tools like compiler and other tools can also be placed there. /usr/java is problematic on the sharp rom because that location is ro.btw, i compiled jikes 1.2.2 which can be used to compile java files.
